    <title language="eng">Interlayer-exciton mediated three-hole-Auger-decay in the pi-band of highly oriented pyrolytic graphite</title>
    <abstract language="eng">Resonant photoemission spectroscopy(resPES) is used to probe the occupied pi- and unoccupied pi*-bands of&#13;
carbon thin films with particular focus on the Auger decay. Highly Oriented Pyrolytic Graphite (HOPG) is&#13;
studied at the C1s edge. We find strong resonant features at 285.5 eV and 292 eV in the resPES diagram. The normal two-hole Auger decay proceeds under constant kinetic energy (451)only in the sigma*-region. In the pi*-region, however, it proceeds under 67.5° in terms of a Ebind(w) diagram. We attribute this to a multiple Auger decay with a net three hole final state. For this novel decay process we propose a model.We discuss&#13;
the long lifetime of the first resonant excitation and conclude that it arises from the strong excitonic character&#13;
of the first resonant state. We use HOPG as a reference system and suggest that this novel process is a tool to&#13;
identify interlayer–substrate interaction of the carbon layers involved.</abstract>
